Indents on either side of nose post under eye filler. Should I dissolve?

The contour that concerns you may be related to migrated filler. If it is, dissolving it with hyaluronidase should help improve it. Skin laxity and volume loss could also impact the look. You can consider Morpheus8 treatments to improve overall skin tone and texture.

Under eye volume loss may be one of the hardest areas to treat. It's best to inject the needed amount of hyaluronic acid once due to the potential bruising in the area. Even after great initial results there can be changes in the area due to sleeping habits and hydration as a result of salty foods or alcohol. If you see any lumps, as in your case, heavy icing and using some hyaluronidase to open up the filler should help. I also recommend some IPL treatment to help with pigmentation and collagen rejuvenation.
Hope this helps. Best, from Boston.

Filler migration, should it occur, typically happens soon after the filler treatment, and so is unlikely the case here. On the other hand, I have personally seen this kind and other variants of filler-related, under-eye problems, known as"puffy pillows," that may occur months to years following treatment. These are believed to be caused by lymphedema or lymphatic obstruction resulting from the use of an inappropriate filler for the under-eye area and/or too superficial placement of the filler in that area.
I have personally had gratifying results in improving this complication with the use of an algorithm of varying combinations, concentrations and amounts of intralesional anti-inflammatory injections.
You would be wise to consult and seek treatment with an experienced, board certified cosmetic dermatologist filler expert. Hope this helps and best of luck.
